those are really great photos, Amanda. What kind of camera do you use?

Amanda, I think you have two different species of shrimp there. The patterning of the stripe is very different in the one that has the red eggs. But, of course, one would need to verify that under the microscope.

Could very well be. Those are, after all, the "mystery shrimp".

But after a week of carrying eggs, wouldn't you assume that they were viable? If they hadn't been fertilized, wouldn't they have dropped by now? So whatever they are, they're breeding with each other.

Well a Japonica shrimp would carry eggs for 5 weeks before releasing them ... you might have to wait a little longer than Amanda ...

Hey amber

That's if they're fertilized. If they're not fertilized, I think they would drop them right away. Which is why I think they have been fertilized. (fingers crossed)

Today, the one carrying the red eggs is blue with a white stripe, same as in the pics on the 1st page. Cool.

amanda_h,
i agree, your pics are fantastic! what do you feed your shrimp, specifically asking because of the outstanding color on the cherry in the group pic... ideally mine will color up more as they mature, but man... that has to be the most "cherry" colored cherry i've ever seen. great pics and great shrimp!

Thanks Oqsy!

Unfortunately, they don't all look like that. That's definitely my cherry-est shrimp.

Mostly they just forage for algae, but after reading some comments here about feeding, I bought them some Hikari Crab Cuisine & frozen spinach. They love 'em! I've also tried giving them bits of all of the different fish foods I have, and the only one they go for is the Sera Discus Pellets. It's cute to see them grab one and run away from all the other shrimp!

That I can imagine, shrimps when it comes to food - first come first served comes to mind

Check it out, I got some pics of the mystery shrimp larvae. Sorry for the fuzziness -- keep in mind these guys are only about 1.5mm long...

Post by **Mustafa** » Thu Nov 04, 2004 4:22 am

Interesting....are they floating around in the water column most of the time or are they primarily sitting on the ground or the glass?

How long has it been (approximately) since they hatched?

I am trying to roughly determine if they can survive in freshwater or not. These larvae look more developed than your typical "primitive" shrimp larva, which requires brackish water or salt water.

Take care,
Mustafa

These pics were taken the first day they were released (I think). The last time, they were all floating around in the water column. This time, for whatever reason, several of them decided to attach themselves to the front glass. Last night a lot more were released, and those were mainly in the water column.

And last time, none of them survived. Although, as you pointed out upthread, I could very well have more than one "mystery species". And also pointed out upthread, I had two shrimp pregnant at the same time -- one with tan eggs and one with red eggs, so these larvae could be a mix of the two. Maybe one is more developed than the other?

To the naked eye they just look like a speck with a tail.

I was planning to convert my 6g to saltwater to try to rear these guys, but I haven't set it up yet.

I guess we'll just have to see what happens again...

Hi Amanda,

Yes, you could well have two shrimp species breeding at the same time. I guess we'll just have to wait and see if the little guys clinging to the glass will develop into mini-shrimp at some point.

Keep us up to date.
